CROSS-REFERENCE TO RELATED APPLICATION

The present application claims benefit of Chinese Patent Application No. 201811321741.4, filed on Nov. 8, 2018, the contents of which are hereby incorporated by reference in their entirety.

BACKGROUND

A spinning process is not strange to manufacturers of aluminum alloy wheels and can obtain wheels with higher performance than wheels manufactured by a pure casting process. This mode is being promoted by more and more enterprises. However, in a spinning production process, a very large spinning flash will be often formed at the top end of a spun wheel due to the influence of a series of factors such as temperature, process and equipment. If this spinning flash is not removed in time, it will seriously affect the production efficiency of machining procedures and aggravate the influence on cutters and machine tools. Therefore, there is a need for an online cutting device for a wheel spinning flash, which can quickly cut and remove the spinning flash of the wheel and provide a regular wheel blank for subsequent procedures.

SUMMARY

The present disclosure relates to a cutting device, and more particularly relates to an improved online cutting device for a wheel spinning flash.

The present disclosure aims to provide a wheel spinning flash cutting device, which may automatically cut a spinning flash of a wheel on line and quickly.

In order to achieve the aforementioned objective, the technical solution of the present disclosure is as follows: a wheel spinning flash cutting device, consists of a rack, a turnover cylinder, a connection rod, a top plate, a first guide rail, a sliding plate, bearing pedestals, first shafts, rollers, a clamping cylinder, a first motor, a belt wheel, a base, a synchronous belt, second shafts, second rails, a support, a cutting blade, a second motor, a feed cylinder and a bracket. The sliding plate, above which the two bearing pedestals are fixed, is connected with the top of the top plate through the first guide rail. The first shafts, above which the rollers are respectively mounted, are fixed in the bearing pedestals through bearings. An output lever of the clamping cylinder fixed above the top plate is connected with the sliding plate. Similarly, the two bearing pedestals are mounted above the base fixed above the top plate, and the first motor is fixed below the base. The second shafts, above which the rollers are mounted and below which the belt wheel is fixed, are fixed in the bearing pedestals through bearings. The first motor drives the two second shafts and the wheel to rotate through the synchronous belt.

A cylinder body of the turnover cylinder is hinged to the rack, and an output lever of the turnover cylinder is hinged with the connection rod below the top plate. The support, on which the second motor is fixed, is connected with a platform of the rack through the second rails. The cutting blade is fixed at the output end of the second motor. The feed cylinder is fixed on the bracket above the rack, and an output lever of the feed cylinder is connected with the support. The second rails, the support, the cutting blade, the second motor and the feed cylinder form a cutting feeding unit of the device.

In a working process, a sensor initially locates the wheel; the clamping cylinder enables the two first shafts to move rightwards; the rollers lift up the wheel away from a roller way and then clamp the wheel; the turnover cylinder enables a turnover frame and the wheel to turn over by degrees through the connection rod to cause the wheel to be in a vertical state; then the first motor drives the wheel to rotate; and after the spinning flash is removed under the action of the cutting feeding unit, the wheel may automatically fall into one side of the rack.

The present disclosure may realize an online cutting function for a wheel spinning flash during use to improve the production efficiency of a machining procedure, and has the characteristics of advanced process, high automation degree, simple structure, low manufacturing cost, safe and stable performance and the like.

DETAILED DESCRIPTION

Details and working conditions of a specific device provided according to the present disclosure are described below in combination with accompanying drawings.

The device consists of a rack 1, a turnover cylinder 2, a connection rod 3, a top plate 4, a first guide rail 5, a sliding plate 6, bearing pedestals 7, first shafts 8, rollers 9, a clamping cylinder 10, a first motor 11, a belt wheel 12, a base 13, a synchronous belt 14, second shafts 15, second guide rails 16, a support 17, a cutting blade 18, a second motor 19, a feed cylinder 20 and a bracket 21. The sliding plate 6, above which the two bearing pedestals 7 are fixed, is connected with the top of the top plate 4 through the first guide rail 5. The first shafts 8, above which the rollers 9 are respectively mounted, are fixed in the bearing pedestals 7 through bearings. An output lever of the clamping cylinder 10 fixed above the top plate 4 is connected with the sliding plate 6. Similarly, the two bearing pedestals 7 are mounted above the base 13 fixed above the top plate 14, and the first motor 11 is fixed below the base 13. The second shafts 15, above which the rollers 9 are mounted and below which the belt wheel 12 is fixed, are fixed in the bearing pedestals 7 through bearings. The first motor 11 drives the two second shafts 15 and the wheel to rotate through the synchronous belt 14.
